Sen. Chris Murphy ripped the NRA and Apple on Tuesday, demanding the computer giant reclassify an NRA-produced shooting game it has labeled appropriate for children as young as four.

“The NRA seems intent on continuing to insult the families of the victims of Sandy Hook,” the Connecticut Democrat said in a statement. “How could they think it was a good idea to use the one month anniversary of the tragedy at Sandy Hook to release a game that teaches four year olds to shoot assault weapons? No matter what outrageous new tool they use, the NRA cannot make a straight-faced case that sport shooters need military-style weapons to enjoy their hobby.”

The NRA released “NRA: Target Range” on Sunday. The game offers users a shooting practice feature, as well as a database of stage gun laws and safety tips. It gives users a chance to fork over 99 additional cents to upgrade their virtual weapon from an M9 to a Baretta, Browning or Colt. Apple ruled the game was appropriate for kids ages 4 and up because it contains “no objectionable content.”

Murphy sent a letter to NRA executive vice president Wayne LaPierre and Apple CEO Tim Cook asking for Apple to reclassify the game.

The game “allows individuals to shoot targets in a variety of settings and with a number of different weapons, including handguns, an AK-47 and an M-16,” Murphy wrote. “In particular, the M-16 is the military version of the Bushmaster AR-15, which was used in the shooting at Newtown. As a parent of two young sons, one of whom is four years old, I find it appalling that this type of app is deemed acceptable for young children.”

Murphy also accuses the NRA of hypocrisy, which condemended violent video games in a speech responding to the Sandy Hook Elementary massacre, which left 26 victims dead, including 20 first graders.

“In his remarks after the shooting, Mr. LaPierre noted the role that violent video games play in de-sensitizing our society,” Murphy wrote. “It is the height of irony that now the NRA is releasing a game that teaches kids as young as four years old to shoot an AK-47. Your organizations can play a role in beginning to change the culture of violence and gun glorification that plagues our society, by recognizing that selling this type of ‘game’ contributes to the problem.”

Murphy represented Newtown in he U.S. House at the time of the shooting.
